Threaded plug for a closure assembly



FIG. 1 is a perspective view of a threaded plug for a closure assembly showing my new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a left side elevational view thereof, the right side elevational view being the same;

FIG. 4 is a front elevational view thereof, the rear elevational view being the same;

FIG. 5 is a sectional view taken along line 5—5 of FIG. 2; and,

FIG. 6 is a bottom plan view thereof.

The broken lines in FIGS. 1, 2 ans 5 depict a grip member used to facilitate installation and removal of the plug and do not constitute any part of the claimed design. 

I claim the ornamental design for threaded plug for a closure assembly, as shown and described.
